I jumped from 9.5 to 10.5 a few weeks ago on my 4 node P4300G2 cluster. I have seen about a 60% reduction in disk latency on each of my VMware hosts as reported by the vSphere management client. As much as it seems 10.5 was not a huge improvement in terms of feature set, the engineers really did improve performance! I heard from an HP employee that they changed the checksumming process to improve performance by simplifying it with 10.0 and 10.5.
